To all whom it may concern:

Be it knownthat we, MOGENS LOUIS BRAMSON, JAMES J HANSON, and THOMAS BETEELL CALDWELL, ty, the Kin of. Great Britain, and residents of Sta ord, in the county of Stafi'ord, En land, have invented certain new and use 1 Im rovements in Flexible Pipe ich the following is a specifi- This invention relates to ball and socket joints particularly for flexible pipe lines and has reference wherein the ball member is provided with a packin ring and the parts are held in assemble position by an annular cap.

' The object of our invention is to provide a plpe having flexible joints of the aforesaid neral character which will be comparatlvely lightin weight, siderable internal ressure without leakage or without its flexibility being unduly imaired, will be ca able of being easily coiled or transport an which,.moreover, will be comparatively easy and cheap of manufacture and durable in use. The primary feature of the present invention consists in pprtion only forming the ball member of a of a ball and providing a pac ng washer resting upon and formm an extension of the inner end of the bal member so that its area is directly subjected to the full re within the pipe. The invention rther comprises a pipe line com osed of ich consist of a socket carried by or forming art of one section and a or ball carried by and formin part of another adjacent section and a leather or other packing washer which when in position forms an extension-of the inner end of the ball member of the joint and is subjected to the pressure of the fluid within the pipe whic operates to maintain it in po'sitrom In the accompanying drawings wev have ipe constructed in accordance illustrated a odying the essential feature of our invention.

In these drawings Fig. 1 is a longitudinal section of a pipe line showing two of the joints between the sgctions, rand Ffig. 2 is a perspective view. 0 va ortion o a pipe line showing the joints Eetween the pipe sections.

subjects of His Majesto ball and socket joints will sustain con-' part only of a sp ere.

Referring to these drawings the numeral 1 designates therigid pipe sections which are flexibly connected together. by our special joints which comprise a cup or socket -member 2 rigidly connectedas by the screw connection 3 to the, end of one of the sections 1 while a portion of a ball or-sphere 4 for co-operation with this cup or socket 2 is rigidly secured, for instance, as by the screw connection 5 to the adjacent end of the next section, of the pipe section protruding throu h a hole in the ball or sphere member and f )rming a means for positioning a leather or like packing washer 6, a bearing rin ,7 screwed into the end of the socket mem r 2 serving to keep the parts in osition and provide adequate bearing su ace for the ball or sphere member of the joint. The washer 6 is preferably an ordinapy washer rectangular 1n cross section, but 1t will be seen from Fig. 1 of the drawings that when once pressed into its operative position in compressive engagement with the inner wall of the cup or socket its peripheral vform conforms to that of the ball or sphere members of the joint, and in eflect this washer 6 forms an extension of the ball or sphere portion. It will be seen that in operation this washer is subjected 'to the full pressure of the fluid within the ipe which tends to maintain it compresse tightly in position It will be understood t ends of the pipe may be provided with more or less usual connection 'fitments such as the union nut 8 or screwed spigot 9.

What we. claimxand desire to secum by Letters Patent is a -1. Aflexible pipe comprisin rigid pipe sections, a cup member dispose at theend of one section, a portion of a ball disposed at the adjacent having a flat inner end, a flat flexible and distortable washer of rectangular crom section disposed on said flat mner end and forming anextension of the ball portion said washer being open to the pressure in the ipe line, the adjacent rigid pipe section of the ball portion extending through said ball ortion and constituting a spi t'over which the said flat flexible .distortab a washer is positioned, and a bearing ring adapted Y to en age the open end of the cup member and. nce the all member into operative engagement with the interior face of the the end 1 at the I end of the adjoining section snrnnnn cALnwnnn, or i act cup member so that the peripheral edge of the flexible washer conforms to the curvature of such interior face.

2. A flexible pipe comprising sections, a cup member disposed of one section, a portion of a at the adjacent end of the adjoining section having a flat-inner end, a flat flexible and distortable washer of rectangular cross section disposed on said fiat inner end and forming an extension of the ball portion, said washer being open to the resshre in the pipe line, the adjacent rigi pipe section of the ball portion extending through said ball portion and constituting a rojecting spigotover which the said flat exrigid pipe at the end ible and istortaole washer is positioned,

ball disposed 1,soo,ea1

and a bearing ring having a concave annulus conforming to the surface of the bell adapted to screw into the open end of the cup member and force the ball member into operative engagement with the interior face of the cup member so that the peripheral edge of the flexible washer conforms to the curvature of such interior face and the ball. member including the washer coo erates with a containing cup formed b t e inner surface of the cup) member an concave annulus of the earing ring.

In witness whereof we aflix our signatures. MOGENS LOUIS BRAMSON. JAMES HANSON. THOMAS BETHELL CALDWELL.
